How do I add multiple nics to set up a router wuth netcfg

Only all I get with multiple files is rnetlink answers file exists.

I don't seem to be able to find much usefull information on the best way to do this to ue Arch as a router.

(It was easy before)

Write a suitable profile for each interface. You can't have multiple interfaces in one profile.

(It's still easy - just different )

Right, so a profile for each interface? That's easy in principle but what would be in each one? Are there examples around?

I get the rnetlink answers file exists error with multiple profiles (one for each interface).

You can get creative with the POST_UP command:

CONNECTION='ethernet'
DESCRIPTION='A basic static ethernet connection using iproute'
INTERFACE='eth0'
IP='static'
ADDR='192.168.1.5'
NETMASK='255.255.255.0'
GATEWAY='192.168.1.1'
DNS=('192.168.1.1' 'X.X.X.X')
DOMAIN='domain.org'
POST_UP='ip addr add 10.200.1.49/26 brd 10.200.1.63 dev eth1 label eth1'
PRE_DOWN='ip addr del 10.200.1.49/26 dev eth1 label eth1'

It's not pretty, but it allows both interfaces to be configured with one profile.

Impossible to answer that without details of what you're trying to achieve. "use Arch as a router" is extremely vague.

Also, please post error messages exactly as they appear on your system - paraphrasing, spelling errors, etc just complicate matters.

Well i got it running with 3 ethernet devices this way :

ll /etc/network.d/
-rw-r--r--  1 root root  178 19 юни  5,17 eth0
-rw-r--r--  1 root root  178 19 юни  5,17 eth1
-rw-r--r--  1 root root  110 19 юни  5,17 eth2

note: my configuration is eth2 - internet device eth0 and eth1 are local net

cat /etc/network.d/eth2 
CONNECTION='ethernet'
DESCRIPTION='A basic dhcp ethernet connection using iproute'
INTERFACE='eth2'
IP='dhcp'

cat /etc/network.d/eth0
CONNECTION='ethernet'
DESCRIPTION='A basic static ethernet connection using iproute'
INTERFACE='eth0'
IP='static'
ADDR='192.168.1.1'

eth1 is same as eth0
note: only problem so far is that if eth0 or eth1 does not have anything connected to them they seem to fail
